Given a number N. Find the minimum number of squares of any number that sums to N. For Example: If N = 100 , N can be expressed as (10*10) and also as (5*5 + 5*5 + 5*5 + 5*5) but the output will be 1 as minimum number of square is 1 , i.e (10*10).

**Example 1:**

**Input:** N = 100
**Output: **1
**Explanation: **10 * 10 = 100

**Example 2:**

**Input: **N = 6
**Output: **3
**Explanation = **1 * 1 + 1 * 1 + 2 * 2 = 6

**Your Task:**

You don't need to read or print anyhting. Your task is to complete the function **MinSquares()** which takes N as input parameter and returns minimum number of squares needed to make N.

**Expcted Time Complexity: **O(N * sqrt(N) )

**Expected Space Complexity: **O(N)

**Constraints:**

1 <= N <= 10000

Here is some troubleshooting advice:

- Reset the IDE using the second button on the top right corner.
- Avoid using static/global variables in your code as your code is tested against multiple test cases and these tend to retain their previous values.
- Passing the Sample/Custom Test cases does not guarantee the correctness of code. On submission, your code is tested against multiple test cases consisting of all possible corner cases and stress constraints.
- You can access the hints to get an idea about what is expected of you as well as the final solution code.
- You can view the solutions submitted by other users from the submission tab.
